Five new water-soluble amido- and aminoanthraquinone pigments, hypalocrinins A–E (1–5), the new amidoanthraquinone biaryls hypalocrinin F (6) and hypalocrinin G (7), and the known compounds 6-bromoemodic acid (8), crinemodin (9), and crinemodin sulfate (10) were isolated from the deep sea crinoid Hypalocrinus naresianus collected off Japan. The structures of the compounds were elucidated by NMR spectroscopy and mass spectrometry. Amido- and aminoquinones are quite unusual among natural products. The hypalocrinins are the first naturally occurring anthraquinones and anthraquinone biaryls conjugated with taurine.

Hypalocrinins，牛磺酸结合蒽醌和联颜料从深海海百合Hypalocrinus naresianus

五个新的水溶性酰氨基和氨基蒽醌颜料，hypalocrinins A-E（1 - 5），新amidoanthraquinone的联芳基hypalocrinin F（6）和hypalocrinin G（7），和已知的化合物6- bromoemodic酸（8），crinemodin （9）和硫酸克林莫德（10）是从日本海域收集的深海海百合类Hypalocrinus naresianus中分离出来的。通过NMR光谱和质谱法阐明了化合物的结构。酰胺基和氨基醌在天然产物中非常不常见。羟色胺是与牛磺酸缀合的第一种天然存在的蒽醌和蒽醌联芳基。
